Nonlinear Theory of Elastic Plates provides the theoretical
materials necessary for the three plate models-Cosserat plates,
Reissner-Mindlin plates and Kirchhoff-Love plates- in the context
of finite elastic deformations. One separate chapter is devoted to
the linearized theory of Kirchhoff-Love plates, which allows for
the study of vibrations of a pre-stressed plate and the static
buckling of a plate. All mathematical results in the tensor theory
in curvilinear coordinates necessary to investigate the plate
theory in finite deformations are provided, making this a
self-contained resource.
Maximum Dissipation: Non-Equilibrium Thermodynamics and its
Geometric Structure explores the thermodynamics of non-equilibrium
processes in materials. The book develops a general technique
created in order to construct nonlinear evolution equations
describing non-equilibrium processes, while also developing a
geometric context for non-equilibrium thermodynamics. Solid
materials are the main focus in this volume, but the construction
is shown to also apply to fluids. This volume also: * Explains the
theory behind thermodynamically-consistent construction of
non-linear evolution equations for non-equilibrium processes *
Provides a geometric setting for non-equilibrium thermodynamics
through several standard models, which are defined as maximum
dissipation processes * Emphasizes applications to the
time-dependent modeling of soft biological tissue Maximum
Dissipation: Non-Equilibrium Thermodynamics and its Geometric
Structure will be valuable for researchers, engineers and graduate
students in non-equilibrium thermodynamics and the mathematical
modeling of material behavior.
Active Disturbance Rejection Control of Dynamic Systems: A Flatness
Based Approach describes the linear control of uncertain nonlinear
systems. The net result is a practical controller design that is
simple and surprisingly robust, one that also guarantees
convergence to small neighborhoods of desired equilibria or
tracking errors that are as close to zero as desired. This
methodology differs from current robust feedback controllers
characterized by either complex matrix manipulations, complex
parameter adaptation schemes and, in other cases, induced high
frequency noises through the classical chattering phenomenon. The
approach contains many of the cornerstones, or philosophical
features, of Model Free Control and ADRC, while exploiting flatness
and GPI control in an efficient manner for linear, nonlinear,
mono-variable and multivariable systems, including those exhibiting
inputs delays. The book contains successful experimental laboratory
case studies of diverse engineering problems, especially those
relating to mechanical, electro-mechanical, robotics, mobile
robotics and power electronics systems.

Pipeline engineers, operators, and plant managers are responsible
for the safety of pipelines, facilities, and staying on top of
regulatory compliance and maintenance. However, they frequently
need reference materials to support their decision, and many new
pipeline engineers and plant managers are responsible for major
repairs and decisions yet do not have the proper reference to set a
holistic integrity plan in place. Pipeline Integrity, Second
Edition delivers necessary pipeline inspection methods,
identification of hazard mechanisms, risk and consequence
evaluations, and repair strategies. Covering relevant standards and
processes for risk, assessment, and integrity management, this

This book, which has only one very distant forerunner authored by
David A. Hills with David Nowell, represents a very big step that
is the quantification of these problems and represents the
twenty-five years' worth of work which have gone on at Oxford since
the first book on the subject. Fatigue (popularly 'metal fatigue')
is the primary failure mode of all machines, engines, transmissions
and indeed almost all mechanical devices. The propagation of cracks
is well understood and is treated in the subject Fracture
Mechanics. By contrast, the nucleation of cracks is very hard to
quantify and this remains the case with so-called 'free initiation'
and, to a lesser extent, at cracks nucleated from stress raising
features. But the third form of nucleation, where cracks start from
the edges of rubbing components, that is, at joints, is potentially
a very much better-defined environment, and therefore, the problem
is amendable to attack by applied mechanics and experiment. The
contents are of value both to those embarking on research on the
subject and to practitioner in industry.
This multi-contributed volume provides a practical,
applications-focused introduction to nonlinear acoustical
techniques for nondestructive evaluation. Compared to linear
techniques, nonlinear acoustical/ultrasonic techniques are much
more sensitive to micro-cracks and other types of small distributed
damages. Most materials and structures exhibit nonlinear behavior
due to the formation of dislocation and micro-cracks from fatigue
or other types of repetitive loadings well before detectable
macro-cracks are formed. Nondestructive evaluation (NDE) tools that
have been developed based on nonlinear acoustical techniques are
capable of providing early warnings about the possibility of
structural failure before detectable macro-cracks are formed. This
book presents the full range of nonlinear acoustical techniques
used today for NDE. The expert chapters cover both theoretical and
experimental aspects, but always with an eye towards applications.
Unlike other titles currently available, which treat nonlinearity
as a physics problem and focus on different analytical derivations,
the present volume emphasizes NDE applications over detailed
analytical derivations. The introductory chapter presents the
fundamentals in a manner accessible to anyone with an undergraduate
degree in Engineering or Physics and equips the reader with all of
the necessary background to understand the remaining chapters. This
self-contained volume will be a valuable reference to graduate
students through practising researchers in Engineering, Materials
Science, and Physics. Represents the first book on nonlinear
acoustical techniques for NDE applications Emphasizes applications
of nonlinear acoustical techniques Presents the fundamental physics
and mathematics behind nonlinear acoustical phenomenon in a simple,
easily understood manner Covers a variety of popular NDE techniques
based on nonlinear acoustics in a single volume

This book presents essential methods of deformation compatibility
control, and explicitly addresses the implied conditions on the
methods' deformation compatibility. Consequently, these conditions
can be considered in engineering structure design, while the
conditions on stable equilibrium can be taken into account in the
design method. Thus, the designed deformation and the actual
deformation of the respective structure are approximately
identical, guaranteeing both the flexibility of the construction
material in force transmission and the equilibrium of force in the
structure. Though equilibrium theory in engineering structures has
been extensively studied, there has been comparatively little
research on compatibility. In the limited researches available, the
topics are primarily the theories and assumptions on the
deformation compatibility, while few systematic works focus on the
mechanical theoretical principles and methods of deformation
compatibility control. As such, the flexibility of the construction
material in force transmission and the stable equilibrium of the
structure as a whole cannot be guaranteed based on these research
results. Successfully addressing this important gap in the
literature, the book is intended for researchers and postgraduates
in engineering mechanics, civil engineering and related areas.

Guide to the Design, Selection, and Application of Screw Feeders
was initiated by the Department of Trade and industry under the
auspices of the British Materials Handling Board, who perceived a
very real need for a practical guide to designing, selecting, and
using screw feeders. It offers the reader clear and accessible
advice - whether seeking a standard screw feeder for a well-proven
application, or designing from scratch for a new duty where no
prior experience can be drawn upon for performance verification.
Screw feeders today play an increasingly important role in the
drive towards improved quality, reduced costs, increased capacity,
better working conditions, and flexibility in solids processing.
Solids feeding operations are a key industrial activity, but are
renowned for operating difficulties that are quite unrelated to the
capital cost of the equipment. Accurate, reliable performance of
gravimetric feeders can both improve the quality and consistency of
a product through close control of ingredient materials and offer
impressive savings through reduction of 'give-away' or
'over-delivery' of product to filling machines. Clear and well
structured Has international appeal Practical - drawn from
experience Well illustrated Offers solutions to real problems This
Guide offers invaluable information to industrial companies that
process and handle bulk materials and to equipment manufacturers -
including design and process engineers, plant and production
managers, and maintenance engineers who are seeking to optimize
performance of production plant. Lyn Bates is an internationally
recognized expert in the field of bulk solids handling and
particularly screw feeders. He is Managing Director of Ajax
Equipment Limited, a company that specializes in screw-type
equipment for solids handling. He is a member and past chairman of
the Institution of Mechanical Enginners Bulk Materials Handling
Committee and has published many papers on subjects ranging from
powder test devices to developments in solids storage and handling.
